@Esa,

Thanks for clarifying! Your explanation about `ClientAliveInterval` and `ClientAliveCountMax` is spot on. It’s important to understand that these settings help check if the client is responsive rather than just tracking inactivity.

The `ClientAliveInterval` does not monitor inactivity but rather checks if the client is still responsive. It sets a timeout interval in seconds; if no data is received from the client during this time, `sshd(8)` will send a message through the encrypted channel to request a response from the client. The default value is 0, which means these messages will not be sent.

For further clarification, the documentation for `ClientAliveCountMax` is helpful:

If `ClientAliveInterval` is set to 15 seconds and `ClientAliveCountMax` is left at its default value, unresponsive SSH clients will be disconnected after approximately 45 seconds. Setting `ClientAliveCountMax` to 0 disables connection termination.
